OIL-RING- Specification of Letters Patent.

To all whom it may concern.-

Be it known that I, HENRY Gnlssnnonnn, a citizen of the United States,residing at Schenectady, county of Schenectady, State of New York, haveinvented certain new and useful Improvements in Oil-Rings, of which thefollowing is a specification.

The object of my present invention is the production of an oil-ring forlubricating shaft-bearings, which is comparatively light in weight,cheaply made, and possesses excellent mechanical and operatingqualities.

The various features of my invention are pointed out with particularityin the claims annexed to and forming a partof this specification. Forabetter understanding of my invention, however, reference may be had tothe drawings, in which I have illustrated one of the forms in.which myinvention may be embodied.

Of the drawings, Figure 1 is a sectional elevation of a journal shaftbearing and suprting-box. Fig. 2 is a sectional elevation taken at rightangles to Fig. '1. Fig. 3 is an elevation with parts broken away and insection of an oil-ring, and Fig. 4 is a plan view showing amodification.

ReferringI to the drawings, 1 represents a pillow-bloc of the usual formprovided at its upper end with a bearing-box 2. In the bearing-box 2 theusual supporting member 3 supports a bearing 4 proper, which may beformed in two parts and be provided with the usual soft-metal lining 5.-In the bearing 4 and lining 5 a shaft 6 (shown in dotted lines in Fig. 1and in full lines in Fig. 2) revolves. Passages 7, which may be of theusual form, aie provided in the upper portion of the bearing 4 and linin5.

Circular oil-rings 8 exten through the passagfs 7. The oil-rings 8,which are considera ly larger in diameter than the shaft 6, on the up rside of which they rest, surround the Tfiwer portion of the bearing anddip into the lubricating material 9 contained in the lower portion ofthe bearing-box.

In the form in which my invention is shown iii the drawings eachoil-ring is made in two similar segmental parts or sections 10. Each ofthe sections 10 is formed of two semicircular pieces 11 of material,such as sheet-brass or the like, L-shaped in crosssection, which arermanently secured togather. As is clear y shown in Fig. 3, each piece 11comprises a radial portion 12 and a portion 13, projecting at rightangles from the nnier edge of the radial portion-that is, one leg of theL is radial and one leg is parallel to the axis of the ring. The pieces11 forming each section of the ring are reversely placed, so that theradiai portions 12 come together. The pieces 11 forming each half of thering are secured together in any suitable manner, as by means of rivets'14 passing transversely through the radial portions 12 of the member.In securing together the parts 11 forming each half of thecollector-ring one end of one of the parts is extended by thecorresponding end of the other piece. As shown in Fig. 3, the right-handpiece 11 of the upper section 10 (shown in the drawings) projects by theleft-hand piece. As before stated, the parts or halves of the oil-ring10 are similar in construction and are assembled with the projectingends of the pieces 11 overlapping. In the construction shown in Figs. 2and 3 the overlapping pieces 11 of the sections 10 are connectedtogether by bolts 15 and nuts 16, each bolt passing through the radialortion of one piece 10 of one half and throug1 the radial portion of theopposite iece 10 of the other half. In practice one olt 15 andcorresponding nut 16 may be replaced by a rivet connection, as shown inFig. 4, suflicient clearance being left between the adjacent abuttingends of the pieces 10 to allow of relative movement of the parts of thering about the rivet as a hinge.

In lacing the oil-rings in )laco in the hearing tiie oil-rings are 0 noat one or more joints and are threade through the passages 6, afterwhich the parts of the ring are all socured together. As is clearlyshown in Fig. 3, the convex corner at the junction of the radial portion12 and corresponding portion 13 of each piece 10 is rounded. Thisresults in the formation of a small V-shaped groove 17 in the innersurface of the oil-ring proper, extending all the way around the ringbetween the two circular parts composed each of the pieces 10, the endsof which abut to gather. The convex corners of the pieces 10 are roundedin the form shown, because it is easier in shaping the material to forma round corner than a square corner and because the groove formed as aresult of the rounded corners increases the amount of oil carried by,the oil-ring from the supp y at the bottom of the bearing-box to thesurface to be lubricated as the ring is rotated by the shaft.

It will be observed that with the construction shown an oil-ring isobtained having the proper width measured parallel to the shaft 6 togive it stiflness in that direction and give it the proper amount ofsurface engaging the shaft and that the pro er stiffness in a and is ceapl radial direction is obtained y means of the radial portions 10. Asa result the oil-ring has the proper oils-carrying surface area and theproper mechanical strength and rigidity made and much lighter in weightt an t e oil-rin substantially rectangular in form hereto orecommonly-,used. The advantage in weight of my construction over thatheretofore in common use is skilled in the art that changes may be madein the form in which I have shown my invention as embodied without dearting from the s irit of my invention, and do not wish the c aimshereinafter made to be limited to the particular construction shown morethan is made necessary by the state of the art.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is-

1. An oil-ring made in arts or sections each part being formed 0 twoarc-shaped pieces secured together so that one en of each piece projectsby the corresponding end of the other piece, and means on securing thetwo parts together.

2. An oil-ring havingma circumferential goove formed in its sft-engaging sur- -3. oil-ring formed out; oil; sflzeeet metaland'comprising a cylindrica s a ngaging portion and a radial portionextending there- 4. An oil- 0 formed of curved pieces of metal L-sha incross-section, one leg of the L in each piece extending parallel to theshaft, and the other leg radially.

5. An oil-ring formed of two circular parts each circular part beingL-shaped in crosssection with one le of the L parallel to the axis ofthe leg an the other leg of the L radial thereto, the radial portions ofthe two parts being placed side by side and secured together.

6. An oil-ring formed of two circular parts, each circular part beingL-shaped in crosssection with one le of the L parallel to the axis ofthe leg an the other leg of the L radial thereto, the radial portions ofthe two parts bein placed side by side and secured together, t e convexedge of one of said parts being rounded.

7. An oil-ring made in parts or sections each section being formed ofarc-shaped pieces secured together with one end of one piece projectingby the corresponding end of another piece,.and means for securingtogether the projecting ends of adjacent sections.

8. An oil-ring made in parts or sections each section being formed ofare-she pieces secured together with one end of one piece projecting bythe corresponding end "of another piece, and means for gether the-proecting ends or ad acent sections.. A

9. An oil-ringmade in two halves or sections, each section being formedof two semicircular arc-shaped pieces secured together",

with the end of one iece projecting by the corresponding end 0 the.other piece, and means for securing the projecting ends of adj acentsection ends together.

10. An oil-rin formed of two circular parts, each circu at part beingL-shaped in cross-section, with one leg of the L parallel to the axis ofthe le and the other leg of the L radial thereto, t e radial rtions ofthe two etparts being placed side y side and secur together and theconvex edges of the parts being rounded whereby a circumferential grooveis formed in the shaft-engaging portion of the oil- In witness whereoflhave hereunto set my hand this 4th day of April, 1905.
